The Acratech Quick-Release Lens Plate - 3" Long is an Arca-compatible support for a tripod mount for a long lens. To form a complete quick-release system for the lens tripod mount, the 3" long plate works with Arca-style clamps from Arca-Swiss, Kirk, Wimberly, Really Right Stuff, Foba and heads from other manufacturers that accept the Arca-Swiss mount.
Equipped with two 1/4"-20 screws, this 3" long plate is suitable for lens collars with mounts that are 3" long or slightly shorter. Acratech camera plates are very lightweight, precision-machined and are well-suited to large and medium format, digital and 35mm SLR cameras for applications for which weight and fitment are key considerations, such as nature photography and landscape photography.
